  • Patent number: 4318444
    Abstract: An agricultural implement is disclosed which includes a center section and a plurality of wing sections foldable with respect to each other. A plurality of ground-working tools extend downwardly and rearwardly from the sections of the implement at spaced intervals along the lengths thereof. The wing sections are pivotally connected to the center section by a telescoping hinge which prevents the ground-working tools of the respective sections from conflicting with each other when the implement is folded. The telescoping hinge includes a telescoping member, slidably connected to an end of a first associated section and pivotally connected to an end of a second associated section adjacent to the first associated section.
